' The present invention relates to dispensing containers for lubricatinggrease. and the like and has particular reference to an improvedcontainer to which a grease gun lubricator may be temporarily attachedfor filling.

An object of the invention is the provision of a dispensing container ofsimple construction wherein the fitting for the gun lubricator is made apart ofan inner floating disc which after functioning to dispense thegrease may be sealed whereupon it becomes a closure so that the coverwhich sealed the container during shipment and storage may be entirelydiscarded after the container is once opened for use.

Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which, takenin connection with the accomp ny drawings, discloses a preferredembodiment thereof.

Referring to the drawings:

Figure 1 is a part side elevation and part sec-' tional view of aninitially sealed dispensing container embodying the instant invention;

As a preferred embodiment of the instant invention the drawingsillustrate a sheet metal container comprising a cylindricalbody llhaving a bottom closure i2 secured thereto in a suitable seam It. Theupper P rtion of the body is preferably enlargedasindicatedat llandthisenlarged portion terminates in a smooth outwardly (CL eel-41.5)

Depending tabs}! formed on the the cover extend down adjacent the sideof the container body andare bent inwardly under the curl II and thushold th cover tightly in sealing position on the container.

The gun or follower plate or disc I1 is preferably of sunken panelcharacter having a flat bottom wall section it which at its outer edgemerges into a flange or side wall section 32 having an cular opening it(Figs. 2, 3 and 4) which is 10- cated in the center of the bottom wallsection 3 I. The opening is surrounded by an internally threaded nozzleit which adjacent its bottomend is formed with an inwardly extendingflange 31. The metal of the plate bottom wall ll around the opening llis bent upwardly and outwardly over the flange ll of the nozzle thusforming a suitable scam I! which tightly holds the nozzle in place. Inorder to prevent i and turning of the nozzle in its seam, spacedindentations 3! are bent edge curl 15 which defines the. mouth of thecontainer.

After the container is filled with its contents a gun or follower plateI! is inserted in the container and the latter is'thereafter closed andsealed with a wver II. The cover is preferably formed with a countersunkpanel it which is surrounded by an inverted U-shaped channel section 1ienclosing an annular channel space 12.

The channel retains a resilient sealing gasket 23' formed in the seamwhich permanently interlock the seam parts.

The nozzle is normally closed with a threaded cap llhaving a raisedfinger lug 4! formed therein for screwing the cap into closing position,as

shown in Figs. 1 and 3. A resilient gasket 43 is preferably interposedbetween the cap and the mime seam to provide an airtight joint. Such acontainer is especially designed for lubricating greases and the likewhich are adapted to be fllled into and dispensed from the well knowngrease gun type of lubricator such as disclosed in United States Patent1,692,423, issued November 20, 1928,.to A. T. Shere, on Grease gun,

Such a gun preferably includes e. tubular body A,

having at one end a cover B and at the other end a threaded section 0 onwhich the dispensing nozzle of the gun is secured. Within the gun bodythere is a piston D secured to a piston rod E which extends through thecover B and terminates in a handle F.

In the container of the instant invention the gun itself, after itsdispensing nozzle end has been removed, is adapted to be 'fi-Dplled tothe nozzle of the gun plate ll Ior filling. In such a use the the coverit of the container is first removed by bending back its lugs 25- andlifting the cover outer edge of thus released from its seat on thecontainer. The removed cover may be discarded as it has no furtherfunction to perform after the container is once opened. 7

The cap H is then unscrewed from the nozzle 36 and the threaded end ofthe gun'screwed in place in its stead. The gun may then be readilyfilled upon drawing the piston D upwardly within the gun cylinder bypulling on the handle F. This movement of the piston creates a vacuum atthe opening 35 in the gun plate i'l. Since the entire top of the plateor disc member is exposed to the pressure conditions of the outsideatmosphere the latter forces the plate down against the grease in thecontainer. This pressure created on the grease forces it up into thecylinder of the gun; One stroke of the'gun pistonfills the gun and it isthereafter unscrewed from the plate nozzle and its own dispensing nozzleis replaced ready for use.-

Between fillings the cap ll may be screwed in place within the platenozzle 36 and thereby serves as a reclosure cap for sealing thecontainer against the entrance of air thereinto. The

gun plate thus serves a double function. As the grease is withdrawn fromthe container the gun plate 41 recedes within the container and alwaysremains in contact with the surface level of the rease.

With such a construction of container the filling of the gun may beperformed very rapidly. Since there are no parts other than the gun 1. Adispensing container adapted to receive a piston type lubricating greasegun for filling,

comprising a body member having its upper portion flared outwardly andopen at its top, a removable cover member for sealing said container 3only during shipment and storage, a follower disc disposed within saidbody member and having a peripheral flange in frictional engagement withtents of the container, and a threaded reclosure or follower plate andits nozzle, its construction I is exceedingly simple and in consequenceof this it has been found to be most eiiicient in operation. The bottomof the plate being flat with no parts projecting below it permits theplate to recede to the very bottom of the container so that thecontainer may be entirely emptied of its contents by the use of the gun,

It is thought that the invention and many' of. its attendant advantageswill be understood from the foregoing description, and it will beapparent that various changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.

I claim:

cap for sealing said nozzle in all positions of said disc relative tothe container body when said lubricator is not attached thereto infilling position on said disc.

2. A dispensing container adapted to receive a piston type lubricatinggrease gun for filling, comprising a body member having its upperportion flared outwardly in a section of enlarged diameter terminatingin an open top, a removable cover member for sealing said container onlyduring shipment and storage, a follower disc disposed within said bodymember and having a peripheral flange in frictional engagement with theinterior wall of said body member, said flange being offset inwardlybelow its well engaging portion to provide a peripheral shoulder forreenforcing and strengthening said disc against distortion due topressure exerted thereon, an upstanding cup shaped nozzle having aflange seamed to said disc above its upper surnozzle in all positions ofsaid disc relative to the container body when said lubricator is not inattached filling position on said disc.
